TDF8553J I2C-bus controlled 4 × 50 Watt power amplifier and multiple voltage regulator Rev. 01 — 3 December 2008 Objective data sheet 1. General description 1.1 Amplifiers The TDF8553 has a complementary quad audio power amplifier that uses BCDMOS technology. It contains four amplifiers configured in Bridge Tied Load (BTL) to drive speakers for front and rear left and right channels. The I2C-bus allows diagnostic information of each amplifier and its speaker to be read separately. Both front and both rear channel amplifiers can be configured independently in line driver mode with a gain of 20 dB (differential output) or amplifier mode with a gain of 26 dB (BTL output). www.DataSheet4U.com 1.2 Voltage regulators The TDF8553 has a multiple output voltage regulator with two power switches.
